public void Insert(
RasterImage image
)
image
Image to be inserted in the PDF file.
This method does not use MRC segmentation on the image being inserted into the PDF file. Use the SetCompression method to specify the compression for the segments. For more information, refer to Creating a Compressed PDF File.
This example inserts an image into a PDF document by using user Segments.
